“I believe we have a lot of changes we need to make systemically in this country to get money out of politics,” he said.

Without mentioning his predecessor Mike Bloomberg or the current Republican frontrunner Donald Trump by name, he said it was impossible to raise money without help from donors without being a billionaire.

“While we have a system that requires campaign contributions to run a campaign, unless you are a billionaire or a millionaire, the question is can you go about the work with integrity every single day and the people’s interest first?

“This is what we’ve done in our administration. We have always said ‘the decision is what is right for the people’ and that is how we make our decisions,” he said.

De Blasio went back to the blame game when he was pressed by Couric about the $50,000 donation Jona Rechnitz, an Upper West Side real estate investor that is at the center of the probe, made to de Blasio’s nonprofit, the Campaign for One New York.

“Until we get the money entirely out of the political system, of course we are going to turn to people for donations — big and small,” he said.

De Blasio said he “absolutely” did not dole out any special treatment or favors following the cash influx from Rechnitz, which he vowed to return Friday after The Post revealed it.
